Truth is in favor of you and me; for the truth of our enemies whom we have been serving here in the U.S.A. for over 400 years (whom we did not know to be our enemies by nature) is the truth that the Black Man must have knowledge of to be able to keep from falling into the deceiving traps that are being laid by our enemies to catch us in their way which is opposed to the way of righteous of whom we are members. ~ The Honorable Elijah Muhammad

What, Exactly, Is a 3-D Printer?

Invented in the mid-1980s, it is a printer that uses plastic, wax, resin, paper, gold, titanium—a whole host of materials—instead of ink to create a solid, three-dimensional object. In much the same way that your desktop printer is directed to print the words in a document, the 3-D printer's jets, guided by computer-assisted design (CAD) software, create an object by spraying or squeezing one thin layer of material at a time onto the platform, then melding them into place with a precisely directed laser. As these microscopically thin layers build up, the desired three-dimensional object slowly takes shape.

While 3-D printing is not a fast manufacturing process, it can be highly efficient because there is virtually no wastage. Unlike traditional manufacturing, where material is cut away by machinery or a lathe to create an object, the "additive" process of 3-D printing uses only what is necessary to make the object. This precision results in a finished product that is both more finely made and up to 60 percent lighter in weight—something of particular interest to the aviation industry.  Nationalgeographic.com
